I'm finally getting around to buying some extra sacs for a 23 LSV. What is the optimal setup for wakeboarding?

I've agreed to buy some old style Fly High sacs off of Craigslist but wanted to check here first. I'm picking up 2 750s and a 1,000 lb sac for the bow. Will this be good or is it too much/too little? I'd love to pick up some ProXs but I don't have the budget for it.
